This article describes ROODA (), a virtual learning environment and one of the official Long Distance Education platforms that has been in use since 2005 at the Federal University of Rio Grande do Sul (UFRGS), Porto Alegre, Brazil. It is free software that integrates syncronous and assyncronous interaction/communication tools and publications. In this study, details about institutional demands in relation to long distance education are discussed and ROODA is described with the components that were part of its development such as: modelling and programming, graphic interface and documents for users. Moreover, 19 functions were conceived. Finally, project investigation paths are presented where the platform described is inserted.

20世纪下半叶,受社会变迁、国家权力、村落场域、农民分层等多重因素的交织影响,江西农村宗族的真实面貌及其变迁深深刻上了时代的烙印,但宗族并没有消亡,而始终扎根于农民的观念深处和日常行为中。作为农民群体的一种组织和生活方式,农村宗族亦处在变革与创新之途。 相似文献

20世纪的“文选学”研究曾经出现过三次关于《文选序》的讨论。这三次研讨,使“选学”界对萧统的文学思想,《文选》的选录标准、《文选》与《文心雕龙》、《诗品》、《宋书·谢灵运传论》的关系诸问题均大大深入。回眸这一历史,可使学界从一个特定的角度对20世纪的“选学”研究作一颇有意义的回顾与总结。 相似文献

会计准则制定模式是会计理论研究的重点之一。通过国内、国外相应事例，对会计准则制定的原则性导向和规则性导向进行对比研究，认为规则性导向优于原则性导向，是准则制定模式的发展趋势，也是会计界的努力方向。 相似文献

The value of teachers’ engagement in and with research is long recognised and it is acknowledged that school–university research partnerships are one way of enabling such engagement. But we know little about how research-based knowledge is negotiated into school practices. Here we draw on data from nine ‘research champions’, who are teachers in schools which are part of the Oxford Education Deanery, a research partnership with a university department. Taking a cultural/historical approach, the study examined the strategic intentions and actions in the activities of the champions as they negotiated research-based knowledge into their schools. Data comprised 59 completed templates that described what they did and why. Findings revealed differences between those with close links with senior leaders—who could take a whole-school approach—and those whose reach was restricted by their position in school practices. Nonetheless, all the champions carefully selected and targeted research in ways that reflected their knowledge of local contexts. The findings point to the need to incorporate the champion role into school systems and for universities to value the role as they develop their own research agenda. 相似文献

Focusing on evaluating students’ performance in basic math classrooms, the researchers in this study examined the impact of alternative assessments on learning outcomes in fourth grade Palestinian classrooms. Representing a large sector of education in the Palestinian territories, fourth grade students were randomly selected to participate in the study in which they participated in various math instructional and assessment activities throughout multiple lessons and cycles. Alternative assessment approaches were used including student self- assessment, peer assessment, and teacher assessment in terms of three main achievement levels to measure the extent to which students learned the math concepts by recall and remembrance, ability to apply, and making inferences. Mixed Design ANOVA measures were used to analyze and interpret the results which showed significant trends and correlations across the four cycles of math instruction and indicated that alternative authentic assessment methods have had a positive impact on students’ learning and application of math. Implications for integrating authentic assessment measures as well as peer and self- assessments were drawn in light of the promising outcomes of augmenting student motivation and developing critical life-long skills. 相似文献
